Guns in Counties

City-Data has a list that purports to be the 101 most well-armed counties in the United States. I'm not at all sure it's accurate, since many gun owners wouldn't report owning a gun out of reasonable concern about government watchlists and attempts at establishing a pre-confiscation registry. Still, it's probably as good a list as can be put together. How many crime-ridden hellholes can you find on it?
